PUMP OR MOTOR.

SPECIFICATION forming part of Letters Patent No. 755,353, dated March 22, 1904.

.Application filed February 17, 1903. Serial No. 143,828. (No model.)

To all whom, t nea/y concern:

Be it known that I, LoUIs MARCEL ALBERT BUTIN, a citizen of the Republic of France, and

a resident of Paris, France, have invented new and useful Improvements in or Relating to Pumps or Motors, which improvements are fully set forth in the following specification.

In the United States Patent numberedv 7 26,024, granted to me on April 21, 1903, I described a motor that could also be used as a pump,the construction of which was briefly described as follows: In a sphere are arranged two movable disks, the first movable about an axis at right angles to its plane and passing through its center and the second movable about an aXis lying within the plane of the disk. I/Vhen one of the disks is rotated, the other is caused to participate in its movement, which results in various chambers limited by the disks and by the walls of the sphere changing their areas. These variations of area are utilized for working a motor or a pump.

This invention relates to a pump which can also be used as a motor designed on the same principle above stated, but in which the sphere is reduced to a semispherical casing, one of the disks remaining a complete circular disk and provided with semispherical sectors, while the other is reduced to a half-circular disk.

For this purpose the invention consistsof an improved pump or motor, which will be fully described hereinafter, and finally pointed out in the'claim.

In the accompanying drawings, Figure lis a vertical longitudinal section of a motor. Fig. 2 is a section taken on line 2 2 of Fig'. l. Fig. 3 is a section taken on line 3 8 of Fig. l; and Fig. 4 is a perspective view of the piston of my improved motor, the casing being removed so as to show the arrangement of the wedge-shaped or semispherical sectors intended to fill up the clearances.

Similar letters of reference indicate corresponding parts. Y

Referring to the drawings, A represents the frame of my improved motor, provided with a journal-bearing B and at its upper end and at one side with aface-plate C, to which is attached by screws d or other suitable means a semispherical casing E,provided with a socket F and inlet and exhaust ports G G forthe inlet and exhaust of the fluid to be pumped. A shaft L is rotatable in the journal-bearing B and provided at one end with a pulley M and at the other end with two spherical sectors N, which have somewhat the shape of wedges, joined at their convergent ends n and provided with a groove n at the joining of said ends. Movablein the groove a is ahinge-pin R, itself provided a groove or slot S, engaged by the lower end of a half-disk T, the upper end of which engages with and is movable in a groove or slot T2 of the shaft t, rotatable in the socket F of the casing. Interposed between the half-disk and the hinge-pin are springs U, which serve to maintain a tight joint between the half-disk T and the inner walls of the semispherical casing E., The shaft serves as a driving-shaft when the apparatus is used as a pump and as the driven shaft when the apparatus is used as a motor. By providing the semispherical segments the clearances are filled in, whereby no waste or injurious spaces will be present.

I claim as new and desire to secure by Letters Patent- Y Apump, consisting of a semispherical cas- .ing provided with a socket and with inlet and exhaust ports, a face-plate provided with a central opening attached to said casing, spherical sectors joined at their convergent ends and provided with a groove at the joining of said ends, a shaft j ou-rnaled in the central opening of said face-plate and connected with said spherical sectors, a hinge-pin having a groove movable in the groove of said spherical sectors, a half-disk engaging the groove of said hinge-pin and provided with a shaft rotatable in the socket of the casing, and springs interposed between the lIinge-pin and half-disk, substantially as set forth.

In testimony whereof I have signed this specification in the'presence of two subscribing witnesses.

LOUIS MARCEL ALBERT BUTIX.
